MONOGRAPH OF THE GENUS PERIPATUS. 451 



than the rest (fig. 24). The remaining ambulatory appendages 

 resemble, except in the following points, those of Capensis. 

 The three spinous pads are green, and the middle one is broader 

 than the other two ; the ventral surface of the proximal 

 part of the leg is white, and the papilla? are a bluish green ; 

 the groove at the base is less marked than in Capensis. 



The foot is rather more delicate than in Capensis, and the 

 spines on the ventral side of the base of the claws are placed 

 on two pairs of small papillae (fig. 9). 



The male is distinguished from the female, as in Capensis, 

 by the possession of a white papilla on the ventral side of the 

 legs of the seventeenth pair, in the same position as in 

 Capensis, and the legs of the eighteenth pair are smaller than 

 in the female. So small are they, indeed, that they are hardly 

 distinguishable from the large papillae found near the hind end 

 of the body ; but they bear two claws, and a rudiment of the 

 foot may be made out. 



In the female the legs of the eighteenth pair (fig. 24) present 

 the following features : — The foot seems to be normal and un- 

 reduced, but the leg is much reduced, presenting on the ventral 

 side only three rows of papillae and one spinous pad, which 

 indeed shows, in some specimens more than others, its consti- 

 tution of separate papillae. The pad and papillae are all tinged 

 with green. 



The embryos are much smaller than in Capensis. In pre- 

 served specimens the length of the fertilised ovum is "4 to "48 

 mm. ; and a full sized adult specimen may reach the length of 

 43 mm. The generative orifice is between the rudimentary 

 legs of the eighteenth pair. As a peculiarity in habits may be 

 mentioned the fact that the individuals of this species nearly 

 always coil themselves into a spiral when touched, while Ca- 

 pensis simply contracts and shortens itself.
